CPC
Condensation Particle Counter

Condensation Particle Counters (CPCs) are in situ sensors that measure aerosol particle concentrations. CPCs determine aerosol concentrations by condensing a fluid onto particles, causing them to grow to sizes detectable by optical scattering. Typically, CPCs detect particles from 7 nm to 3 μm, measure concentrations up to 100,000 particles per cubic centimeter, and provide readings every second. CPCs are manufactured by TSI Incorporated and can be used on airborne, shipborne, and ground-based platforms.
